Possible solution
• Check if the packing material is removed from the filter�
• The filter has not been placed in the appliance� Make
sure that the filter (FY3430/30) is properly installed�
• The particle sensor is wet� The humidity level in your
room is high and causes condensation� Make sure that
the particle sensor is clean and dry (see the chapter
"Cleaning and maintenance")�
• Room size is large or the outdoor air quality is poor�
For optimum purification performance, please close the
doors and windows when operating the air purifier�
• There are indoor pollution resources� For instances,
smoking, cooking, incense, perfume or alchohol�
• Filter reaches the end of life� Replace the filter with a
new one�
• The particle sensor is dirty� Clean the particle sensor
(see the chapter "Cleaning and maintenance")�
• The first few times you use the appliance, it may
produce a plastic smell� This is normal� However, if the
appliance produces a burnt smell even if removing
filters, contact your Philips dealer or an authorized
Philips service center� The filter may produce smell after
being used for a while because of the absorption of
indoor gases� It's recommended that you reactivate the
filter by putting it in direct sunlight for repeated use� If
odor still exists, replace the filter�
• It's normal if the appliance runs at the Turbo mode�
• In the Auto mode, if the appliance is too loud, maybe
the appliance runs at high speed because air quality
becomes worse, or your personalized setting in App
triggers a higher fan speed� You can choose the Sleep
mode, or change the settings in the App�
• If there is abnormal sound, contact the Consumer Care
Center in your country�
• If anything drop into air outlet, it may also cause
abnormal loud sound� Immediate turn off appliance,
turn appliance upside down, to get foreign objectives
out of appliance�
